On a quiet Friday morning in the 7-barrel pilot brewhouse at Odell Brewing Company, brewers from Odell and nearby neighbor, New Belgium, gathered together to brew up a hop-forward experimental pale ale—a beer that represents the longtime collaborative spirit between the two Fort Collins craft breweries.

It was a shared passion for exploring new hop varieties that sparked the collaboration, which eventually evolved into a beer that will be served at this year’s Collaboration Beer Festival, a unique beer fest thrown by the Colorado Brewers Guild each year to showcase the talent and spirit of the local craft beer industry. Hops are the main character in this beer story, but over 100 different collaborations are taking place at breweries throughout Colorado and beyond this month—all of which will be served at Collaboration Fest which is set to take place on Saturday, March 25 in the spacious National Western Complex in Denver. Over 150 participating breweries forged more than 100 beer collaborations for this year’s festival.

Tickets are $60 for General Admission, and $85 for VIP. The festival will also include live music and food vendors. Check out the full list of collaborations and snag tickets for this unique event at collaborationfest.com.
